Adobe Create Social Variations

Adobe Create Social Variations

Produces platform-ready images and videos from a single source file. Uses AI canvas expansion and subject-aware cropping to keep the subject in focus across all aspect ratios. Shows a lightweight 3-crop preview before a full-set run so framing issues are caught early — those crops are then reused in the final output.

Surface note: The default flow below uses Adobe's MCP App widgets — the asset_add_file file picker and the asset_preview_file preview. Follow it as written. Only if a widget tool is not available on this surface (e.g. Codex) use the No-widget fallback attached to that step. Likewise, present AskUserQuestion prompts as plain-text labeled options wherever no question widget exists.

Supported Input Types

Step 0 - prereq: Initialize Adobe Tools

Call adobe_mandatory_init first. This returns file handling rules and tool routing guidance required for the rest of the workflow.

{ "skill_name": "adobe-create-social-variations", "skill_version": "2.1.0" }

Step 1 — Entitlement Check

Now that adobe_mandatory_init confirmed that the "Adobe for creativity" connector is live, check which tools are available through the connector and set capability flags.

Image Workflow — Core Tools (required)

All of these must be present for the skill to run at all. If any are missing from the connector, output this message exactly and stop — make no further tool calls:

"To access this skill, please disconnect and reconnect to the "Adobe for creativity" Connector to sign in using an Adobe account, or sign up."

Widget Tools (used when available; graceful fallback)

Image Workflow — Enhanced Tools (optional, graceful fallback)

Video Workflow — Required Tools (optional workflow, all-or-nothing)

Only offer the video workflow if both tools below are available. If either is missing, set videoCapable = false — do NOT mention video resizing capabilities to the user at any point.

If videoCapable = false and the user explicitly asks about video resizing, avoid verbosity and output this message exactly:

"Video resizing isn't available with your current setup. Please disconnect and reconnect to the "Adobe for creativity" Connector to sign in using an Adobe account, or sign up. In the meantime, I can help with image crops and social media variants though."

IMAGE WORKFLOW

Step 0 — Get the Source File

How you get the file depends on where it is:

No-widget fallback (only if asset_add_file is unavailable on this surface, e.g. Codex) — don't ask the user to pick. Stage any local file programmatically (asset_initialize_file_upload → PUT → asset_finalize_file_upload) and use the returned presigned CC URL; for a file already in Creative Cloud, reference it directly by its CC URI. Staging requires egress — check egress status from adobe_mandatory_init first; if egress is disabled and no picker is available on this surface, tell the user staging isn't possible here and ask them to run the workflow on a surface with the asset_add_file picker.

After the file is available, detect image vs. video from mediaType. For images, proceed to Step 1.

Step 1 — Ask: Which Platforms?

Ask in a single question using AskUserQuestion with multi-select:

Full set / Instagram / TikTok / LinkedIn / Facebook / YouTube / Snapchat / X/Twitter / Pinterest / Threads

Set the test flag based on the user's answer:

• If "Full set" is selected → runTestPreview = true. Use all platforms. A 3-crop test preview will be shown before the full set is generated (see Step 4).

• If any specific platform(s) are selected → runTestPreview = false. Use only the selected platforms. Skip the test preview and go directly from Step 3 to Step 5.

The test preview is a useful safety net for large cross-platform batches, but unnecessary friction for a targeted 1–2 platform run.

Step 2 — Inspect Image & Set Focus Strategy

Inspect the image first using asset_inline_preview on the source file. Visual inspection produces far better focus decisions than guessing from the filename — and usually means you won't need to ask the user anything at all.

After inspecting, tell the user what you see and what focus strategy you're using, and invite a correction:

"I can see this is a [e.g. 'product shot of a tote bag on a neutral background']. I'll use [focus strategy] to keep [subject] centred across all crops. Does that sound right, or would you like me to focus on something else?"

Only ask a follow-up question if the image is genuinely ambiguous (multiple equally prominent subjects, or a scene with no clear focal point).

For images containing people, use "face" — prompt-based focus drifts to bodies rather than faces. Reserve { prompt: "..." } for non-human subjects.

⚠️ If the source image is significantly wider than it is tall (landscape), use 2000px top & bottom for the tall expand (not the default 960px) — this gives the portrait crop enough canvas to reframe around the subject. ⚠️ For the same landscape sources, also use 1500px left & right for the wide expand (not the default 960px) — 960px doesn't give the reframe enough room to pull the subject into centre for the ~2:1 landscape crop.

If the user corrects your assessment, update the focus strategy and confirm before proceeding.

Step 3 — Generative Expand (directly from source — no padding)

Expand the original image directly. Do not pad to square first — the AI produces better results extending real scene content than bridging across blank bars.

Run both expands before any crops:

// GROUP A — tall canvas (for 9:16 and 4:5 targets)
image_generative_expand(sourceURI, { top: 960, bottom: 960 }) → tallURI
// use 2000 top & bottom if source is significantly landscape

// GROUP B — wide canvas (for ~2:1 and 16:9 targets)
image_generative_expand(sourceURI, { left: 960, right: 960 }) → wideURI
// use 1500 left & right if source is significantly landscape

Square targets (1:1) crop directly from the source — no expand needed.

Expands originate from the original sourceURI — chained expands degrade output. ⚠️ If image_generative_expand returns 403 (entitlement), fall back to image_crop_and_resize with fit: "reframe" from sourceURI for all variants in that group. Note the fallback in the delivery summary.

Step 4 — Test Preview (Full set only — skip if runTestPreview = false)

If runTestPreview = false (specific platforms selected): skip this step and go directly to Step 5.

If runTestPreview = true (Full set): produce 3 representative test crops — one per aspect ratio family — before generating the full set.

Show all 3 via asset_preview_file and ask:

"Here are 3 test crops covering the main aspect ratios. Do the framing and expansion look good? I'll generate the full set once you approve."

No-widget fallback (only if asset_preview_file is unavailable, e.g. Codex) — present all 3 URLs directly in the message and ask the same question; UI clients render them inline, and in Codex or other non-UI agents, download each to the workspace and reference the local paths.

These crops are reused in the final output — only the 9:16 story/reel crop needs to be generated after approval.

Step 5 — Generate All Platform Variants

If runTestPreview = true: proceed only after user approves test crops in Step 4. If runTestPreview = false: proceed immediately after Step 3.

Generate every variant in the Platform Specs table for each selected platform. Reuse test crop URIs only when dimensions are an exact match — for any different dimensions, run a fresh image_crop_and_resize.

Per-platform variants to generate:

Step 6 — Preview Full Set

Call asset_preview_file with all successfully generated URLs — including partial sets when some variants failed.

No-widget fallback (only if asset_preview_file is unavailable, e.g. Codex) — list all successfully generated URLs directly in the message (including partial sets when some variants failed). UI clients render them inline; in Codex or other non-UI agents, download each to the workspace and reference the local paths.

Step 7 — Delivery Summary

Present a clean summary table. Note any fallbacks or skipped steps clearly.

✅ Social media set complete!

| Platform  | Format         | Dimensions | Status        |
| --------- | -------------- | ---------- | ------------- |
| Instagram | Feed Square    | 1080×1080  | ✅ (from test) |
| Instagram | Feed Portrait  | 1080×1350  | ✅ (from test) |
| Instagram | Story / Reel   | 1080×1920  | ✅             |
| TikTok    | Video / Post   | 1080×1920  | ✅             |
| LinkedIn  | Post Landscape | 1200×627   | ✅ (from test) |
| LinkedIn  | Post Square    | 1080×1080  | ✅ (from test) |

If generative expand fell back to reframe:

⚠️ AI canvas expansion is not included in your current Adobe plan — smart reframe was used instead.

VIDEO WORKFLOW

Step 0 — Get the Source File

Video tools require an assetId — not a URL. How you get it depends on where the file is:

If egress is disabled and the user has already dropped a video into chat, explain why it can't be used directly: "To resize your video I'll need you to select it via the file picker — this gives Adobe the asset ID it needs. I'll open it now."

No-widget fallback (only if asset_add_file is unavailable, e.g. Codex) — stage the local video programmatically (asset_initialize_file_upload → PUT → asset_finalize_file_upload) and use the returned assetId; for a video already in Creative Cloud, reference it by its assetId. Staging requires egress — check egress status from adobe_mandatory_init first; if egress is disabled and no picker is available on this surface, tell the user staging isn't possible here and ask them to run the workflow on a surface with the asset_add_file picker.

Step 1 — Determine Video Type

If the user has already described or implied the video orientation (e.g. "I shot this on my phone in portrait" → clearly 9:16), skip this question and proceed. Otherwise ask:

"To suggest the best output sizes, it helps to know what kind of video this is. What type is it?"

Use AskUserQuestion with single-select:

Step 2 — Suggest Safe Output Sizes

Only suggest same-ratio resizes. Cross-ratio resizes (e.g. 16:9 → 9:16) produce black bars and are algorithmically penalised on TikTok and Instagram Reels. If a user asks for a cross-ratio resize, explain the limitation and offer same-ratio alternatives instead.

Present these as options with AskUserQuestion (multi-select).

Step 3 — Resize

⚠️ resizeVideoPoll is a deferred tool — load it first before attempting to poll. Direct calls without loading will fail with "not loaded" error.

For each selected size, call video_resize with the asset ID:

video_resize({ assetId: sourceAssetId, width: W, height: H }) → { statusId }

Poll with resizeVideoPoll until complete. Poll 3–4 times with brief pauses before reporting slow progress to the user.

Step 4 — Preview

Call asset_preview_file with all completed outputs.

No-widget fallback (only if asset_preview_file is unavailable, e.g. Codex) — list all completed output URLs directly in the message. UI clients render them inline; in Codex or other non-UI agents, download each to the workspace and reference the local paths.

Step 5 — Delivery Summary

✅ Video resize complete!

| Size      | Ratio | Status |
| --------- | ----- | ------ |
| 1080×1920 | 9:16  | ✅      |
| 720×1280  | 9:16  | ✅      |

Note: Video resizing does not apply intelligent reframing — cross-ratio reformatting is out of scope for this skill.

Error Handling

Hard Constraints

• Never pass a raw local filesystem path to any image_* or video tool. Local files must reach Creative Cloud first — selected via the asset_add_file picker, or (no-widget fallback) staged via asset_initialize_file_upload → PUT → asset_finalize_file_upload; only the resulting presigned CC URI (for images) or assetId (for video tools) is valid.
